Maybe it aint so precise, but I think the side of an unbleached or
painted on shipping box or a piece of
corrugated cardboard would do in a pinch....

I just got a macro lens today and want to do some
exposure testing with the istDS flash. I need a
gray card but dont have one.
anybody know of a common household item that
emulates 18% gray or an easy way to make one
with the pc? I have an accurate incident/reflectance
meter so I guess I could just do a bunch of gray
shade printouts till i find the right shade but
that sounds like too much work.
